Tungsten disulfide (WS 2) and Al-doped WS 2 (WS 2 @Al x, x = 0, 2, and 4 wt.%) are prepared by a one-step hydrothermal technique, and the crystal strain of WS 2 was grown by doping Al. The introduction of Al within the framework of WS 2 reduced the diffusion energy barrier and the interface resistance of Mg 2+ ions.
